hey people, I was wondering if anyone knows what would cause a plane to climb when it's level, but also climb when inverted. Im flying my own fan fold foam designed plane, about the 5th one, and they all do it. I've tried adjusting the thrust, right a little, down a little, also zero zero, and ive tried flaps and reverse flaps, and I just can't figure out how to get zero climb, whether its level flight or inverted. Id really appreciate any advice/info on this aerodynamic problem. by the way, I used fan fold foam with plans for an edge 540 from 3dfoamy.com ,and it flies great, so I know the problem I have is in the design, so I was really hoping somebody knew something about design, or where I could go to read up on it myself. Thanx for your answers.
